OSCAR B. GRIFFIN, 0F BLASDELL, NEW YORK.

SHOE-PROTECTOR.

Application led April 17, 1913.

To all whom z' may concern:

Be it known that I, OSCAR B. GRIFFIN, a citizen of the United States, residing at Blasdell, in the county of Erie and State of New York, have invented a certain new and useful Improvement in Shoe-Protectors, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to coverings for shoes, or over-shoes, and more particularly to those used to protect the shoes of men working around furnaces, and has one object, to provide an improved form, and cicient means to protect the workmens shoes from becoming burnt by the hot metal around which they work.

It also has for an object the forming of a permanent arch to be used in ordinary walking shoes.

Similar figures refer to similar parts in the different views.

Referring to the drawing, Figure l is a plan of my improved shoe protector, and Fig. 2 a vertical section through the center line of Fig. 1.

l is the heel portion of the protector upper or counter, and it terminates in the strip 2, which is laced through the tongue, 5, of the toe-cap upper 4, and fastened by a buckle, 3. These different portions of the upper can be made of any suitable material, but in my improvement, I have used leather.

6 is the sole, and 9'the heel, which are made of any suitable noninflammable heat resisting material, which prevents slipping and that is preferably of rubber fiber.

7 and l1 are nonheat conducting inner soles, or filler.

The sole 6 and heel 9 are fastened together by a spring piece 10, by means of the rivets 8. 10 is preferably made of a piece of spring steel which connects the sole and heel, and allows them to conform to the bottom Copies of this patent may be obtained for five cents each, by addressing the Specication of Letters Patent.

of the shoe, and also allows of a certain amount of spring and movement to better facilitate walking than when the sole and heel are more rigidly connected in one continuous piece. This spring piece holds the heel and sole, and is shaped to form a permanent arch.

Having thus described my invention, what I claim and desire to secure by Letters Patent is;

l. In a heat resisting shoe protector for furnace workers and the like, the combination of a non slipping, non metallic and non inflammable sole and heel, a flexible metal shank Shaped to form a heel plate, a partial sole plate and arranged to conform to the arch of a shoe, said non inflammable heel attached to and covering said heel plate, and said non inflammable sole attached to and covering said partial sole plate and the part of the shank conforming to the arch of the shoe, respectively, a filler composed of Inaterial which is a non conductor of heat in the sole and heel, a toe cap attached to said sole, a counter attached to said heel and a strap connecting said counter and said toe cap for holding said protector to a shoe.

2. In a shoe protector, the combination of a sole and heel of non infiammable and non slipping material, a permanent elastic metal arch securely fastened to said sole and heel and connecting them by a vertical portion of said arch which is uncovered and arranged to allow of free movement of the said sole and heel relative to each other to make contact with the ground to prevent slipping, a non heat conducting inner sole in said heel and a non heat conducting inner sole above the portion of said sole which makes contact with the ground, and separate uppers attached to said heel and said sole to protect the heel and toe of a shoe, said uppers connected to retain the protector on a shoe.
